To all whom it may concern: I

Be it known'that I, EpwARD L. MEGILL, a citizen of V the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Gauge Pins, of which the following is a specification.

This inventionrelates to improvements in gauge pins for use in connection with printmg presses and it is in general an improve ment on the invention described in my Patent No. 1,385,637, July 26, 1921.

Devices of the character referred tov are formed for attachment to the tympan sheet of a printing press to serve as position-definsheet and From ing or registering members for the successive pieces of work during the operation of making the printed impressions. The particular type of gauge pin shown in in the present application is made up of two parts, a main gauge member having a pin or prong for attaching the member to the tympan sheet, and a tongue movably mounted on the gauge member to projectva-rious distances over the faceof the work. The gauge member consists of a gauge head or abutment member arranged to take a substantially normal or perpendicular position with relation to the surface of the tympan having a prong extending froma middle portion of the lowermost edge of the head in a direction away from the work.

the uppermost edge of the head extend two arms spaced apart and formed at 'their free extremities with downwardly bent flattened feet or pressure members which are arranged to engage the upper surface of the j the position of the end of the prong. e

The two parallel and laterally separated arms which extend fromthe upper edge of the gauge head serve as supporting members for a tongue which is provided at one eX- tremity with laterally extending hook members which embrace the outermost edges of the arms. The tongue projects forwardly from its'pointed engagement with the arms and extends through an opening provided for the purpose in the gauge head .to a'position abovethe piece of work. The engage-1' ment of the tongue with the arm members is such that the tongue can be moved backwardly or forwardly along the arms to cause the free endthereof to project various dis tances over the face of the were.

the patent and guiding the hook Serial No. 505,479;

One feature of the invention resides in the j construction of the ,arm

members to assist in the I s themselves which a i because of, their disconnected spaced apart free ends provide for a bending of the arms frictional engagement of'the hook members a with the outermost lateral edges 'offlthe arms.

Anotherfeature" of the invention consistsin the provision of laterally extending stop members formed nearthe rearmost portion" of'the arms and which rearward ing accidentally moved out of engagement serve to limit the 1 movement of the tongue member's and to prevent the tongue members from bewith the gauge membersupport; Thelstop" membersreferred to are relatively small and while they serve the I at the same time permit of a sufficient "inward bending of other and together of the hook members to cause the hookmembers to pass over-the'outermost extremities of the stop members to thereby provide foi the removal of the tongue members from the gauge member supports when such removal" is deliberatelyjsoughts Still another featu're of the invention con-' i providing the pressure foot ex f the free ends of the arm with a sists in tremities formation such that it materially assists in members of the tongue into arm engaging to, mount the tongue members ontheir supf assist the assembling or ports To further disassembling of" the tongue memberslfrom their supports a notch or recess isformed in" the outermost lateral edges of the armmem bers between thefstop lugs referred to and the c pressure foot members;-

The arms members which may the free end of the tongue 13 to I or foot members ll and'12 of the arms are pressed toward each other to release the frictional engagement of the hooks and the arms and free the tongue for movement along the arms by finger piece 15. J I To assist inthe freeing of the engagement of thehook members with the arms in order yto provideftor the ready adjustment ofthe tongue member 13,'the base portion 16' of bowed formation portion of the tongue occupies a somewhat elevated position withrelation'to L surface of the arms 8' and 9. It will be, seen that by depressing the'bowed or, 'ele-" .vated portionv of the hook member at the the hook member is given an upwardly socthat normally the base the upper i same time that the extremitiesfof the arms 8 and 9 are pressed toward each other a;

doubly I 1.4- and lateral edges of the armsf8 and 9 is obtained. This is brought'ab'out by the lateral spreading ofthehook'members produced by the flattening of the bowed'pon' tion as indicated in Figures "Sand 6 of the drawing. I 1 .In orderto prevent" the accidental movement oi? the tongue 13in a rearward direc tion to an extent sufiicient to remove the tongue from its engagement with theialrms 17 are formed on the lateral edges of the Y arms 8 and 9. Theselugs serve and stop. further rearward movement hook members 14: when the hook members are brought ,toth'eir rearmostposition.

'lt will be seen that the stop lugs 17jjare" su'l'ficiently small'to permitoftheir passing between the opposing inner faces of the op;

effective releasing action ofthe hooks v to engage I 12 of the arms 8 and I 9 are moved 1nwardly. toward leachother' a sufiicient distance as -,is indicated in Fig-1.

\ It will thus be-seen that by pressing inwardlyitheextremities" arms 8 and 9 and'atthe' same time' depressingthe of the tengue from the supporting bowedportion16 18 a"sufiicient"deformation or" arms. @This feature provides for the ready members having ditferent lengthsrin accordance with ,the re-Y quirements of the workor to repla cefto'ngue v 1 have f become inj'uret or broken. I In order to :t'; ilitate the removal of the hook members 14k from tion with the arms 8 and 9, recesses 18 are'i formed in the lateralledges' of the arms be'rs 17 5 therecesses 18 serving topermlt the th'erethrough of the extreme'tips 19",

passage their engagingposip and 9 just to the rear of the -stopilug'mem-'- or" the hook members 14L aswill be clear. In

i order to assist inguiding thehookmembers' erally extending hook into a position in which they will pass through the recesses 18 in an assembling operation, the pressure foot extremities 11 and 12 of the arms 8 and 9 are formed with a suitably curvedformation to guide the hook members into the recesses 18'.

It willbe seen that I have provided a gauge pin in which the tongue members can readily be interchanged without the exertion of substantial muscular effort by the fingers of the user. This is accomplished by distributing the deformation of parts necessary between both the supporting arm members and the arm engaging portion of the tongue itself'so that a relatively small deformation of each of all the parts is suflicient to produce the requisite clearance for the purpose.

What I claim is: l. In a gaging device for printing presses, a work positioning member, means for attaching the work positioning member to the tympan sheet of a press, a pair of spaced apart tongue supporting arms attached to said member, and a tongue mounted on said arms to extend over the face of the work, said tongue being provided with laterally extending hook members formed to engage the outside edges of the arms, said tongue member between said hook members being formed of resilient metal and normally bowed and said arms being also formed of resilient metal, whereby a flattening of the bowed portion of the tongue and a bending toward each other of the spaced apart resilient arms permits the release of the hooks from engagement with the arms.

2. In a gaging device for printing a work positioning member, means for attaching the work positioning member to the tympan sheet of a'press, a pair of spaced apart resilient arms attached to said member and extending away from the work en gaging portion thereof, a tongue mounted on said arms to extend over the face of the work, said tongue being provided with latmembers formed to engage the outside edges of the arms, said tongue member between said hook members being formed of resilient metal and normally presses,

bowed whereby a flattening of the bowed portion of the tongue and a bendin'g'toward each other of the spaced apart resilientarms releases the frictional engagement of the edges of the arms and the hook members to providefor the adjustment of the tongue along said arms, and stop members provided on said outside edges of said arms near the free ends thereof to prevent the accidental removal of said hooks from the arms, said stop members permitting the passing of the arms being provided with curved feet, atongue mounted on'said arms-to extend'over,

said tongue being proextending hook mem- I bers formed to engage the outside edges of member between said the face of the work, vided with laterally the arms, said tongue v hook members being normally bowed, stop members on said outside edges of said arms hooks thereover' for release at the will of presses,

near said curved feet, recesses in said lateral edges between said stop members and said feet, said'bowed formation of said tongue permitting a flattening thereof and said resilient arms being capable of being bent t0 wardeach other through said recesses, and ,said curved feet being formed to into said recesses.

4. In a work printing presses, an elongated support, a tongue slidably mounted on said support for projection to various extents overthe work, said tongue being provided-with laterally extending hookmembers for engaging the" guide said hook members positioning member for to permit saidhookmembers to pass said stop members and pass lateral edges of the support, and said tongue I member .being bowed between said hook members for the purpose described.
